अविरोधितया कर्म नाविद्यां विनिवर्तयेत् ।विद्याऽविद्यां निहन्त्येव तेजस्तिमिरसङ्घवत् ॥ ३ ॥
In plain words
Action cannot end ignorance — action is not its opposite, so it has no grip on it. Knowledge alone destroys ignorance, the way light destroys a heaped-up mass of darkness.
Close to the Sanskrit
Because of non-oppositeness, action would not remove ignorance; knowledge alone strikes down ignorance, as light a mass of darkness.
